I tried to find a barrow that was marked on the map but which I suspected would be part of an army barracks. A spotty 17 year old on guard duty with an SA80 couldn’t confirm or deny it’s whereabouts but I think this is within an army barracks, and that the area will be strictly off-limits to general visitors. Either that or it may be slightly further south and may not being off limits.....
The site of the Barossa Barracks (see below for some of the history) is now taken up by the amorphous Montgomery Lines barracks, which includes 4 separate barracks; Arnhem Barracks, Bruneval Barracks, Normandy Barracks &, Rhine Barracks.
Judging for the map the barrow seems to be just off the road called ‘Pennyfathers Rd’ on the street map, possibly part of Bruneval Barracks?
The Hampshire County Council website says “north east of the grounds of the prince Consort’s library. 20.0m in diameter and 1.0m high. Trees grow on the perimeter. Barrow mutilated to form band-stand in early 1890s in grounds of the newly built Barossa Barrracks (on site of original hutments). Barossa barracks demolished early 1960s.”
